TO DESTROY A SPACE STATION!

[cyclonebuster]

Well since they moved it I believe the first statement!

 

[MeteorWayne]

This article (had you read it) says there is no <i> IMMEDIATE </i> threat to the space station.<br />In fact in your next post, you link to an article saying the ISS was moved later on.<br /><br />So is it No Threat! or A Threat! ??<br /><br />And what the heck is the point? <div class="Discussion_UserSignature"> <p><font color="#000080"><em><font color="#000000">But the Krell forgot one thing John.

Point is: When an object blows up in space, debris is scattered in all directions. Some may re-enter the Earths atmosphere while others could impact the ISS or any other object in orbit ie (Briz-M sat ) . That is why they moved the ISS.

This is what it sounds like, when bugs fry. <div class="Discussion_UserSignature"> <p><font color="#000080"><em><font color="#000000">But the Krell forgot one thing John. Monsters.

[cyclonebuster]

I guess you think all orbital explosions are no threat to the ISS!!

 

[MeteorWayne]

That would be stupid. I'm not stupid.<br /><br />I know they are.<br /><br /> You've posted links saying they are a threat and not a threat.<br /><br />What do you think? <div class="Discussion_UserSignature"> <p><font color="#000080"><em><font color="#000000">But the Krell forgot one thing John.

[cyclonebuster]

Since the debris can go in all directions any explosion is bad while in orbit!

Congratulations, Obviousman.<br /><br />You want to answer the questions? <div class="Discussion_UserSignature"> <p><font color="#000080"><em><font color="#000000">But the Krell forgot one thing John.

If it were so obvious to you then why did you ask the question?

""Space station moves to avoid debris <br />MOSCOW, Feb. 2 (UPI) -- U.S. and Russian officials changed the International Space Station's orbit to keep it clear of debris from a satellite destroyed by China, a report says." "<br /><br />ISS did not reboost in this case. It was an apparent translation error that it could if there was an issue. There was no issue.

 

[cyclonebuster]

Perhaps, some of this Chinese debris hit this?<br /><br />http://www.space.com/news/070221_rocket_explodes.html?? <br /><br />Perhaps, some of this debris <br /><br />http://www.space.com/news/070221_rocket_explodes.html <br /><br />can hit the ISS?

"It had hypergolic fuels aboard, which tend to be kind of corrosive," Matney told SPACE.com. "That may be it. It's always a possibility that it was a micrometeor or debris hit, but most probably it was just a spontaneous failure." <br /><br />Hypergolic? Interesting.<br /><br />Sometimes spent stages in orbit explode. In another thread on the Chinese ASAT test the explosion of a spent Delta IV upper stage was constantly brought up. That explosion generated less than 100 trackable fragments. It's interesting to note that the exploded Delta IV stage used hydrogen and oxygen propellants.<br /><br />What I'm wondering about the Briz M stage explosion is how such an energetic explosion was able to occur at all. True the Briz M was mostly full of propellant but it's much harder to get a large explosion with hypergolic propellants because they burn on contact. More conventional fuels can form a large intermixed cloud which then ignite from a spark thereby creating a large explosion. <br /><br />I see how the Briz M could have caught fire, but how did it explode? Could something other than the propellant have helped shatter the stage? Bursting pressurization tanks? Maybe it was hit with a large chunk of orbital debris after all?<br />

 

[cyclonebuster]

Perhaps??? Who would know for sure? When will we know more about this?

 

[cyclonebuster]

Stop what? You trying to censor me?

 

[cyclonebuster]

Lets see, even so those globs of propellant would be devastaing to the ISS at those velocities!!

 

[gunsandrockets]

"It might be entirely possible that some of the present debris tracks are glops of the propellant liquids? We'll see when the numbers are refined in a week or two, "<br /><br />That's an interesting notion. What does the Briz M use? UDMH and nitrogen tetroxide? Wouldn't even frozen drops of that stuff pretty quickly evaporate from sunlight heating?

My thread my rubbish. One mans rubbish is another mans treasure!

http://www.astronautix.com/craft/brizm.htm <br /><br />Length: 2.61 m (8.56 ft). Basic Diameter: 2.50 m (8.20 ft). Span: 4.10 m (13.40 ft). Mass: 22,170 kg (48,870 lb). Main Engine: S5.98M. Main Engine: 95 kg (209 lb). Main Engine Thrust: 19.600 kN (4,406 lbf). Main Engine Propellants: N2O4/UDMH. Main Engine Propellants: 19,800 kg (43,600 lb). Main Engine Isp: 326 sec. <br /><br />Interesting. Note the high ISP, considerably better than the Shuttle OMS or the Apollo service module engine.

 

[cyclonebuster]

I would guess made for machine not man. Anyways, thousands of pieces up there not good if you ask me! We may have to make a solar powered laser now to place in orbit to move those pieces back through Earths atmosphere.

DEBRIS SWARM: When a Russian Briz-M rocket booster exploded over Australia on Feb. 19th, astronomer Gordon Garradd was first to report it, and he may have observed the display longer than anyone else--for nearly an hour. That gave him time to take plenty of pictures, which he has stitched together into a remarkable movie. This snippet shows a swarm of fragments expanding around the center of the blast: <br /><br /><br />Photo details: Nikon D200, 85mm lens @ f/1.6, ISO 500. <br /><br />The full-length movie contains much more--a billowing cloud of rocket fuel, hundreds of stars, dozens of fragments, and several bright satellites streaking through the field of view. (How many can you count?) Click to view a medium-resolution 4 MB video or a high-resolution 20 MB video. <br /><br />Experts at NASA and elsewhere are studying these images carefully, both to learn about the physics of satellite break-ups and to track the trajectory of the debris. "There is no immediate threat to the space station," says Mark Matney of NASA's Orbital Debris Office at the Johnson Space Center, "but we're analyzing the orbits to assess any long-term hazard."<br />http://www.spaceweather.com/swpod2007/23feb07/garradd_strip.gif<br /><br />

OK, let's leave the rubbish thread here.
